• A. 354 g
• B. 35,400 g
• C. 3,540 g
• D. 3.54 g

Correct answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1,000 since there are 1,000 grams in a kilogram. Therefore, 35.40 kg × 1,000 = 35,400 grams.

• D. 4:20

Correct answer: C

Rationale: To convert 0.02 to a ratio, you need to express it as a fraction. 0.02 is equivalent to 2/100. Simplifying this fraction gives you 1/50. So, the correct ratio for 0.02 is 1:50. Choice A is correct because it accurately represents the ratio of 0.02. Choices B, C, and D are incorrect: B is not the simplified form of 0.02, C simplifies to 1:50, not 2:40, and D is not the correct simplified ratio for 0.02.

3. What is 0.5 liter in ml?

• A. 500 ml

Correct answer: A

Rationale: The metric prefix 'centi-' signifies 10^-2, denoting one-hundredth of a unit. For instance, 1 centimeter equals 0.01 of the base unit. Choice B, 'milli,' represents 10^-3, 'nano' in Choice C represents 10^-9, and 'deci' in Choice D stands for 10^-1. Therefore, the correct answer is 'centi.'

5. What is 0.125 as a fraction?

• A. 1/8
• B. 1/4
• C. 1/2
• D. 1/16
